It's set to expire again on December 31, 2020.

How Does the Oil Spill Tax Translate to Diesel and Gasoline?

Diesel fuel: 0.2143cts/gal

A 5% biodiesel blend:0.2036cts/gal

B20: 0.1714cts/gal

A typical 10% ethanol blend of finished motor fuel: 0.1929cts/gal

E0 (all hydrocarbon) gasoline: 0.1929cts/gal.

Oil Spill Tax History: Looking Backward

The 9 cents per barrel federal oil spill liability tax has had a bumpy ride lately.

It expired Dec. 31, 2017 and then went back into effect March 1, 2018, after Congress reinstated the tax as part of a congressional budget bill. It expired again on Dec. 31, 2018 and was recently reauthorized.

It's set to expire again on December 31, 2020.

Since its inception in 1986, the tax has been collected on domestic crude oil and imported crude oil and petroleum products as a main source of revenue to fund the Oil Spill Liability Trust Fund to aid in the cleanup of oil spills.

U.S. oil companies exposed to the tax have generally passed along the cost to their wholesale distributors as part of their wholesale rack price or as a separate line item expressed in cents per gallon.

Oil Spill Liability Tax Has Been a Thorny Issue for Industry in Past

The oil spill liability tax has long been a sore spot for the industry, especially when it comes to including the fee as part of the wholesale price or listing it as a separate line item.

The Petroleum Marketers Association (PMAA) in the past has advocated that the tax be embedded in the wholesale rack price and not listed as a separate line item since it is largely a tax on crude oil paid by refiners and producers and not by distributors and jobbers.

Nonetheless, most suppliers have broken out the tax as a separate line item on invoices.
